Traffic signage represents an indispensable component of a public infrastructure system. It is an element that contributes to and supports the operation of the roadway system by guiding, regulating, warning, and indicating the use of the road, promoting smooth traffic flow and ensuring the safety of users. However, traffic accidents frequently occur, resulting in considerable costs to public funds. To understand the causes of an accident, it is essential to investigate its origins by analyzing the factors that lead to traffic conflicts. Through a case study, this work involves the observation, counting, and analysis of the sections where accidents occur most frequently on Av. Jacu-Pêssego/Nova Trabalhadores. The main underlying causes of the registered accidents were identified, and an analysis of traffic conflicts at the studied location was conducted. For this purpose, the recognition and selection of the site for the road analysis were planned, along with the collection of field data, with a focus on observing three types of traffic conflicts: those involving the same direction for right turns, straight movements, and lane changes.It is worth highlighting that the chosen road for this study was selected because it is a crucial route in the eastern zone, connecting highways and interconnecting densely populated areas in the city of São Paulo. Through information guiding the direction and analysis of this study, such as traffic volume and its hourly variations, user actions and reactions to the road, conflict averages, and their significance in the study context, road conditions, among other aspects, opportunities for improvement were identified. These improvements can be implemented on the road by adjusting signage and maintaining existing elements, thereby reducing conflicts and accidents with minimal intervention at the location
